To all whom it may concern:

Be it kn`own that I, WILHELM FRIEDRICH LUDWIG BETH, manufacturer, a subject of -the German Emperor", residing at Lbeck,

,and down may not take lace at each revolution of this cam-shaft, ut at eater inter vals, these cams are displacea ly mounted on the shaft and may be moved to and fro thereon by means of a suitable operating mechanism, so that each lever is only encountered at long intervals by the respective lift-cam. This longitudinal displacement of the cams on the shaft involves drawbacks, as it produces considerable sliding friction,owing to the encrusting-or fouling' of the parts displaced, and thus `wastes a considerable amount of power. y

Now thisy invention'has for its object an arra ment which .avoids the said drawbaclg the means hereinafter described.

In t e accompanying drawings various forms of construction are shown in Figures l to 9.

vThe form of construction shown in Figs. 1

' to 3 is" a vertical sectionof the arran ement in various positions. A two-armed ever t, which carries the' tubular trunk orfilter a, is mounted'on a rocking lever lc in such a Way that 'it is only encountered by the rotating cam d at stated or determined times-that is to say, when thislever k is brought into the positlon shown'in Fig. 2 in any suitable manf ner by means ofthe opera-tin parts-.-for instance, by the rotating camisk Z byv means of a push-rod m.A When thecam d releases the'lever b, it passes intothe positionjsho'wn in Fig. 3,'and'on the further rotation of the the position shown in Fig. l. f l

FIgs. 4, 5, and 6 show another form of con- ,4 struction. Anoscillatin contactnismounted on a lever b, which oes'not' itselfcomev cam-disk l the lever 7c is again 4brought intof into contact with the cam d. In the osition shown in Fig. 4 a rotating cut-out 'sk o f holds the oscillating contact n erect'or upright; but in the posltion shown in Fi 5 this disk has released ity andit has droppe down, so that it is encountered b the cam d, and so tips up the lever b. In i 6 the action of the cam d has ceased, the Iever b has tilted back into its initial position, and on the f u1'' lther rotation of the disk o the condition shown in Fig. 4 is restablished..

The form of construction shown in Figs. 7 i

to-9 is similar. The lever b is pivotally displaceable in an oval slot p. cut-out disk o holds this lever!) in the raise position, as shownin Fig. 7, `in which it is not encountered by the .'cam d. In'Fig. 8 the .disk o has allowed the pivot/or axis of rotation to drop, whereby the `free end of the le- A ver. l) comes into the path of the cam d, and conse uently the lever is tilted u After the re ease by the cam d the lever assumes the position shown in Fig. 9 until the disk o again raises Fig. 7.
